Mitt Romney promised Latinos on Thursday that he would swiftly reform the American immigration system -- once again without saying whether he would end President Obama's policy allowing some young undocumented immigrants reprieve from fear of deportation. "Some people have asked if I will let stand the president's executive order," Romney said at the National Association of Latino Elected and Appointed Officials conference. Romney incorrectly referred to the policy change as an order from the president instead of a directive to agencies dealing with immigration.
